OWI AMP1SGB in-wall amplifier
For you out there with the whole-home custom installs who have run out of receiver channels of your universe or are simply unwilling to run amplified audio everywhere throughout the compound, OWI has a clever in-wall amplifier to power up your in-wall speakers and maintain that invisible audio system look. The AMP1SGB is a 25-Watt Class AB amp that can drive four speakers and fits in a double-gang box right inside your wall; all you need to do is find a plug for the wall-wart. It's definitely convenient, but we'd be willing to bet it's not the last word in audio quality, but seriously, when was the last time you were let down by the audio quality in your bathroom?
